ATTACHMENT FOR NCHES.

SPEGIFICATION forming part of LettersPatent No. 608,256, dated August 2, 1898.

Application filed June 25, 1897.

useful Attachment for Punches, of which the following is a specification.

The invention relates to attachments for punches especially adapted for use by conductors or other officials of a railroad.

The object of the present invention is to provide a punch with a magnifying-glass to be used for deciphering small printed matter the instrument by a single stem or rod. Fig.

on a ticket, partly-obliterated writing or signatures thereon, and other matter on the ticket, as well asfor magnifying purposes generally, the attachment being so arranged or combined with the punch that when the latter is held in position for operating on a ticket themagnifying-glass may be used.

without changing the position of the punch in the hand.

A further object of the invention is to arrange the magnifying-glass within the limits of the punch Without interfering with the operation of the same and to avoid any projectin g parts, so that the instrument may be readily carried in the pocket without liability of injuring the magnifying-glass.

Another object of the invention is to enable the spring, which holds the punch in position for operating on a ticket, to be also employed for retaining the lens in place.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

To enable others to understand my invention, I have illustrated the same in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a perspective view of a punch, showing myattachmentappliedthereto. Fig. 2 is a seotionalelevation showing the preferred construction by which the pressurespring and the lens are held in position within 3 is a detail view of the stem or rod detached from the instrument. 1

Like letters of reference denote correspond- Serial No. 642,344; (Ndmodch) .ingpartsin all the figures of the drawings,

referring to Which A designates the punch. B is the lens, and O is the holder or frame by which the lens is attached to the punch within the limits of the levers or handles thereof.

The punch A may be of any suitable construction, asthe punch proper forms no part of my present invention. Asshown in the drawings, the punch consists of two levers or members constructed to form jaws at one end and to cross one'another to adapt the members to be pivoted together and thus form the handles ct Ct, by which the implement can be readily grasped Withinthe'hand, so as to force the jaws together to force the punch-die G through the ticket fitted in the slot g.

According to my invention I provide an attachment by which small,obscure, or partly obliterated matter on a ticket or other object may be enlarged and made visible to the conductor or other person using the instrument. The attachment comprises the lens B and the frame or holder 0, which receives the lens within itself and which is attached to the inner face or side-of oneof the handles a of a suitable form of punch, whereby the magnifying attachment is arranged to be inclosed Within the limits of the punch, and it does not interfere with the operator in grasping and manipulating the instrument.

The lens-holding means is combined with the pressure-spring to serve as a guide therefor. The invention embraces a novel construction of the rod or stem D-that is to say, the rod consists of a straight elongated shank (Z and a loop .or eye 01, which is bent to a shape proper to receive within itself the lens B. The extremity of the stem or rod beyond the lens-holding loop 61 is attached rigidly to the outer end of one'of the handles a of the instrument; but the other end of said stem D is fitted loosely in a slot or opening e, provided in the other handle a, at a point close to the fulcrum of the two members or levers of the punch. The straight portion of the stem or rod is thus arranged to extend diagonally'across the space between the two han dles, and one end of said rod is fast with one of the handles, while the other. extremity thereof is loosely or slidably connected to the other handle, whereby the stem is adapted to have a limited endwise movement when the members or levers are forced together or spread apart. On the straight shank (Z of the stem or rod is loosely fitted a coiled spring E, one end of which is seated against the loop (7 of the stem. The other end of the coiled spring bears against the handle (L at the point where the free end of the stem plays loosely in said handle, and thus the spring operates to press against the two handles to normally force them apart.

From the foregoing description it is obvious that the stem or red serves as the means for fastening the lens 13 to the instrument within the handles thereof, and it also serves the purpose of holding the pressure-spring E between and in operative relation to the two handles of the instrument. The loop or eye (1 of the stem fits tightly around the peripheral edge of the lens, except for a short dis tanee, where the lens abuts or bears against the inner face of the handle, to which the outer extremity of the rod or stem D is attached rigidly in a suitable way.

The coiled spring, besides operating tohold the handles normally separated, also serves to cause the eye or loop to clamp the lens.

It will be observed that I have combined a magnifying-lens with a punch in such a way that the lens is not in any way obstructed or obscured by the punch-handle and the means by which it is attached to said handle, and at the same time the lens and its holding means are arranged within the limits of the instrument to be out of the way when the instrument is grasped and operated.

I am aware that changes in the form and proportion of parts and in the details of 0011- struction may be made without departing from the spirit or sacrificing the advantages of my invention, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with a punch, of a stem bent upon itself at its rear portion to provide a divided loop or eye and secured at the rear side of the eye to the adjacent handle, said stem having a straight diagonal portion extending across the punch to the other handle and slidably connected with the same, a lens arranged within the loop or eye, and a coiled spring mounted on the straight diagonal portion of the stem and interposed between the eye or loop and the opposite handle, whereby the handles are held normally separated and the lens is also clamped within the said loop or eye, substantially as described.

In testimony that I claim the foregoing as may own I havehereto affixed mysignature in the presence of two witnesses.
